Operation principle of the present utility model is: the core component of circuit is M668 control chip, and its internal circuit is mainly made up of synclator, frequency counter, control logic circuit three parts. Inner oscillating circuit starting of oscillation is in lock-out pulse shortly past zero point, and failure of oscillation approaches next zero point in lock-out pulse. When power supply has just been opened, internal circuit automatically resets, and 7 pin no pulse outputs, in low level state. When 2 pin are subject to for the 1st time to touch, branch frequency counting circuit is counted oscillating impulse, during to the 7th pulse, jumps as high level on 7 pin, until lock-out pulse approaches zero crossing and returns to low level, the angle of flow of unidirectional thyristor Q1 is very little. While being subject to for the 2nd time to touch, when branch frequency counting circuit is counted to the 5th pulse to oscillatory meter, jump as high level on 7 pin, the angle of flow of unidirectional thyristor Q1 is larger. While being subject to for the 3rd time to touch, 1st step-by-step counting of branch frequency counting circuit to vibration, jumps as high level on 7 pin, and is maintained to lock-out pulse and approaches zero crossing, and the angle of flow maximum of unidirectional thyristor Q1, can reach more than 150 °. When the 4th is subject to touch, branch frequency counting circuit stops counting, and 7 pin no pulse outputs, are equivalent to shutdown. Its speed governing program is undertaken by above-mentioned level Four do action. If 4 pin of IC are connect to power positive end, only there is above-mentioned triggering for the 3rd, 4 times alternately to complete on/off function. It both can touch quoit A with hand triggers 2 pin.
Supply with the dc source of IC1 and be by resistance R 3 current limliting step-downs, Zener diode D2 voltage stabilizing at 6.8V, diode D2 isolation, supplies with the stable DC voltage of 6V after C2 filtering. Formed the internal clock frequency of oscillation of about 1.5kHz by Resistor-Capacitor Unit R7, C5, supply with inner output, counting frequency dividing circuit. By providing the defeated people of lock-out pulse of 100Hz to 5 pin of IC1 after R2, R6 dividing potential drop, internal oscillator and counting frequency dividing circuit are synchronizeed with supply frequency, produce phase-shift pulse output taking zero crossing as benchmark, thereby change the angle of flow of unidirectional thyristor Q1, reach the object that changes direct current generator M rotating speed.
